UN DETALLE SIN IMPORTANCIA:
Why did John du Pont really shoot wrestler Dave Schultz?
The movie falsely implies that Mark Schultz leaving Foxcatcher and ending his association with du Pont had something to do with du Pont's anger toward Mark's brother Dave. In reality, Mark had been gone from Foxcatcher for more than six years at the time of Dave's murder. 36-year-old Dave Schultz had been coaching other wrestlers at Foxcatcher, in addition to training for his final attempt at gold in the 1996 Summer Games in Atlanta. He, not Mark, was the closest thing John du Pont had to a friend. Du Pont grew upset when Schultz announced that he was leaving Foxcatcher after the Olympics to accept a coaching job at Stanford.
